Series of 'unofficial' accusations during the starting period of HBL PSL 5

An allegation without solid proof is ethically unacceptable thing which
Mr. Roy has done

My question is why Gora's always accuse Pakistanis off a 'baseless' accusation of tempering the ball, as always? I admit there have been instances where the Ancestral Pakistani bowlers did so and there is no denying that but when there is no proof of the same, accusing someone off such insulting the whole nation, no doubt it was done in the past but the current Pakistani breed of bowlers unable to do so because of the current rules and regulations and the two balls from each end defies bowlers to do so, and the exception is atmospheric support, air resistance, and dusty ambiance which could support such swinging, where Karachi is no exception, because those who have been to Karachi or live in this city would definitely admit that we experience four seasons in a day, especially during the transition period where the weather at Karachi city is under transition in between Winters, Spring and somewhat Autumn therefore we have been experiencing both Winters, Springs and Autumns in span of 24 hours. We wake up in cold so that we need to switch off our fans, by 10 am in the morning, it is slightly warm like in springs, and by the mid-noon, it is touching 30s and by evening it is moist because later on we have the dew factor, therefore there are natural instances by which a cricket ball can swing and that too with the fact that mostly Karachi and its sister city i.e. Hyderabad Sindh are known for the evening winds which are both soothing and calming.

As far as I am concern

In that regards, if Mr. Roy thinks that pointing fingers only at Pakistanis would do them some harm, he has been living under the stones I guess, because this is the same thing Freddy Flintoff did and was awarded with loads of trophies and monuments citing he is a magician etc. I don't have any grudge with that but the fact is if we are accepting his achievement as achievement that better accept others achievement as achievement too. There is a give-and-take-rule for everything, same rules applies here.

What should the PSL Management be doing?

They should refrain players be involved in such conversations, because such things occur in nick of angry minds' therefore this is the high responsibility of the on-field invigilators i.e. the umpires for avoiding such unpleasant and sour taste experiences on the field. The fault lies with them instead of the players because it was the incapable gesture of these invigilators because of which this thing occurred. SO the PCB and PSL management should look into this on a serious note.
